RFFC5061/62

WIDEBAND SYNTHESIZER/VCO WITH

INTEGRATED 6GHz MIXER

The RFFC5061 and RFFC5062 are re-configurable frequency conversion devices

with integrated fractional-N phased locked loop (PLL) synthesizer, voltage con-

trolled oscillator (VCO) and either one or two high linearity mixers. The fractional-N

synthesizer takes advantage of an advanced sigma-delta modulator that delivers

ultra-fine step sizes and low spurious products. The RFFC5061 and RFFC5062

have been designed to use an external crystal, typically 26MHz, and have inte-

grated programmable loading capacitors. The PLL/VCO engine combined with an

external loop filter allows the user to generate local oscillator (LO) signals from

85MHz to 4200MHz. The LO signal is buffered and routed to the integrated RF mix-

ers which are used to up/down-convert frequencies ranging from 30MHz to

6000MHz. The mixer bias current is programmable and can be reduced for applica-

tions requiring lower power consumption. Both devices can be configured to work

as signal sources by bypassing the integrated mixers. Device programming is

achieved via a simple 3-wire serial interface. In addition, a unique programming

mode allows up to four devices to be controlled from a common serial bus. This

eliminates the need for separate chip-select control lines between each device and

the host controller. Up to six general purpose outputs are provided, which can be

used to access internal signals (e.g. the LOCK signal) or to control front end compo-

nents. Both devices operate with a 2.7V to 3.3V power supply.
